Objective To investigate the association between podocytes and proteinuria in children with Alport syndrome. Methods Twenty-one children including 13 boys and 8 girls with Alport syndrome were divided into 3 groups according to 24-hour urinary protein, ＜30 mg/kgas the mild proteinuria group (10 patients), 30 to 50 mg/kg as the moderate proteinuria group (4 patients) and ＞50 wg/kg as the heavy proteinuria group (7 patients). The correlation between foot process width and the degree of proteinuria was analyzed. By immunoperoxidase staining on renal tissue, the key slit diaphragm molecules nephrin, podocin and podocyte cytoskeleton-associated molecule synaptopodin were studied. Results The foot process width (420-2270 nm) in patients with Alport syndrome was positively correlated with proteinuria significantly (r=0.765, P＜0.01).Foot process width was significantly lower in patients with mild proteinuria [475 (420-900) nm)compared with that in patients with heavy proteinuria [1520 (480-2270) nm] (P＜0.05). In Alport syndrome children with heavy proteinuria, the distribution of nephrin and podocin changed dramatically. In two children with shorter proteinuria period (1 year), dramatic distribution change of nephrin and podocin occurred, however, the foot process along with synaptopodin preserved.Conclusions Podocyte foot process effacement and injury of slit diaphragm participate in the mechanism of proteinuria in Alport syndrome. The injury of slit diaphragm seems to be an early event in the development of foot process effacement in Alport syndrome, which may guarantee early treatment.

BACKGROUND:Statins can promote the mRNA expression of bone morphogenetic protein 2, aggrecan and type II col agen in intervertebral disc cel s, and they also can reverse the phenotype of dedifferentiated nucleus pulposus cel s to slow disc degeneration process. OBJECTIVE:To review the research progress of simvastatin modulating the biological characteristics and mobilizing endogenous stem cel s for the repair of intervertebral disc degeneration. METHODS:The first author retrieved the PubMed and CNKI databases for relevant articles published before January 2016 using the key words of“disc degeneration factor, Simvastatin AND stem cel s, endogenous stem cel s AND disc degeneration”in English and Chinese, respectively. Initial y, 102 relevant articles were retrieved, but only 48 articles were included in result analysis fol owing elimination of duplicate studies.RESULTS AND CONCLUSION:By summarizing a large number of studies on the treatment of intervertebral disc degeneration worldwide, we found that simvastatin may modulate the biological characteristics and function of nucleus pulposus mesenchymal stem cel s via promoting the expression of hypoxia-inducible factor 1αfor the endogenous stem cel-based therapy of intervertebral disc degeneration.

BACKGROUND:Vertebroplasty and kyphoplasty have been widely applied in the treatment of osteoporotic thoracolumbar compression fracture. However, cement leakage is a major problem in the application of this technology, especial y for the vertebral posterior wal ruptured patients. OBJECTIVE:To investigate the therapeutic efficacy of high viscosity bone cement and vertebroplasty in the treatment of osteoporotic thoracolumbar compression fracture. METHODS:A retrospective study was conducted in 20 cases receiving high viscosity bone cement and vertebroplasty surgery for osteoporotic thoracolumbar compression fracture. Clinical outcomes were evaluated mainly with use of Visual Analog Scale for lower back pain. Function of lower back pain was assessed using Oswestry Disability Index questionnaire. Quality of life was evaluated using 36-Item Short Form Health Survey and Frankel score was applied to evaluate neurological function. The anterior vertebral height of the fractured vertebrae was assessed with X-ray. The bone cement leakage, pulmonary embolism, incidence of nearby vertebral fractures and other complications were evaluated during fol ow-up. RESULTS AND CONCLUSION:Al patients were fol owed up for 12-18 months. The anterior vertebral height of the fractured vertebrae, the lower back pain and function, and quality of life were improved significantly after treatment (P<0.05). Al patients got the same neurological symptoms before surgery. The bone cement dispersion was good after treatment, detected by X-ray and CT scan, only two cases appeared with bone cement leakage, but no clinical symptoms were found. There was no cement toxicity or al ergic complications, pulmonary embolism, infection, nerve injury or new fractures. The high viscosity bone cement used in the treatment of osteoporotic thoracolumbar vertebral compression fractures can significantly relieve thoracic back pain, improve lower back function and quality of life, and greatly reduce the risk of bone cement leakage.

BACKGROUND: Percutaneous vertebroplasty has been gradual y used to treat Kümmel disease because of less trauma and quick pain relief, but there is stil a high rate of bone cement leakage. OBJECTIVE: To investigate the clinical efficacy of percutaneous vertebroplasty with high-viscosity bone cement plus hyperextension position reset for treatment of Kümmel ’s disease. METHODS: The clinical data of 17 patients with Kümmel ’s disease were retrospectively analyzed, including 5 males and 12 females, aged 55-83 years, and al underwent percutaneous vertebroplasty with high-viscosity bone cement plus hyperextension position reset. The visual analog scale, Oswestry disability index score, vertebral body height and vertebral kyphosis angle were determined. The bone cement leakage, pulmonary embolism, adjacent vertebral fractures and other complications were recorded. RESULTS AND CONCLUSION: At the 12th Oswestry disability index scores and vertebral kyphosis angle of patients were significantly lower than those before treatment (P < 0.05), the vertebral body height was significantly higher than that before month of follow-up, the visual analog scale scores, treatment (P < 0.05). After treatment, there were three cases of bone cement leakage, which had no special discomfort and neurological symptoms, and one case of new fractures. These results demonstrate that hyperextension position reset combined with percutaneous vertebroplasty with high-viscosity bone cement in treatment of Kümmel ’s disease can effectively relieve back pain, improve function of the lower back, partial y restore vertebral height and reduce kyphosis angle.

As a biomaterial to be used for reparation in the case of trauma, the silk fibroin, particularly its effect on the transcription and expression of VEGF gene, is a concern. In this study, the ECV304 cell's growth shape and growth curve on the regenerated silk fibroin film were observed, and its VEGF secretion level was measured by ELISA test. It was found that the regenerated silk fibroin film did not interfere with ECV304 cell's growth and function. The L929 cell transfected with human VEGF gene grew on the regenerated silk fibroin film; the real-time quantitative RT-PCR method and ELISA test were used for detecting the transcription and expression of VEGF gene. The results showed the regenerated silk fibroin film did not interfere with the transcription and expression of VEGF gene. Therefore, the regenerated silk fibroin film is a safe biomaterial for inducing vascularization with no untoward effect on the reparation of trauma.

Our primary health care institution began to implement national essential medicine system in 2009. In past fi ve years, the goal of national essential medicine system has been initially achieved. For examples, medicine price is steadily reducing, the quality of medical services is improving and residents' satisfaction is substantial increasing every year. However, at the same time, we also found some urgent problems needed to be solved. For examples, the range of national essential medicine is limited, which is difficult to guarantee the quality of essential medication. In addition, how to compensate the primary health care institution is still a question.
